True, "fluoroelastomer" sounds fancier than saying "synthetic rubber".
Thanks. Okay then. I concede they do have such a patent, and that I could be very wrong. Mark this day
All Apple has ever said is that it's
"up to twice as hard as standard gold." There's no such thing as "standard gold", and they didn't specify a karat, so I assumed they were comparing to "pure gold".
However, perhaps they simply want to avoid saying that they're mixing powered gold with a powdered ceramic, to form an 18kt equivalent composite material that's not all metal.
Why not? Would people look down on such a gold alloy? Actually, I guess they probably couldn't even call it an "alloy" since it's not all metal. The patent calls it a "mixture", mixed in a mold and heated up.
